A use-after-free bug in the Chromium Network Service lets a remote attacker corrupt heap memory using a crafted HTML page. Exploitation can lead to code execution inside the browser, and this bug is confirmed exploited in the wild per CISA KEV.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Google Chromium Network Service affected ? fixed ?
- vendor:google chrome affected < 105.0.5195.52 fixed 105.0.5195.52
- vendor:fedoraproject fedora affected = 37 fixed ?

## How to check

Open the browser's version page (chrome://version or edge://version) and compare against the patched release named in the vendor advisory; the sources do not give a version number.

## Fix

Update Google Chrome, Microsoft Edge, Opera or other Chromium browsers to the latest vendor release as CISA directs.
